[sdiy] PCB faceplate large hole creation?

[doug at synthark.com]

I'm building a jack faceplate, which requires large holes (MIDI, USB).  
While I can create the holes in my PCB tool (DipTrace), it flags most of 
the holes as DRC violations (too large to drill, > 0.2"), which makes 
sense, since PCB fabs probably aren't setup to drill large holes.  I'm 
guessing my best solution would be to CNC the PCB after it's fab'd 
(since the USB hole is not circular).  Can anyone confirm or provide a 
better solution?

Thanks,
